Is this with the case buttoned up? Or with the top off? Putting the top on 
the case makes a significant difference in level!

Are you using the LED power indicator on the K2, or an external averaging 
meter? The LED indicator shows PEAK, not average.

There may well be little difference in the PEAK reading, but there should 
be a noticeable increase in the AVERAGE. With the Heil mic, I'd expect you 
to be able to set SSb A to 1 (maybe 2, but probably NOT required), and to 
run SSb C at 2 to 3.
